Although the Evo's battery is longer then the Health E, the threading is the same. The Health E fits in to the USB charger of the Evo. The carts and atomizers seam to be interchangeable as well.
I was just wondering if anyone else has tried this and has had any problems I need to be aware of.
Thanks

As long as the center posts touch, and the charger is rated at 4.5V @ 1000mA it should be fine.
I'm not to sure how "on topic" this is but if the Health E is anything like the eHealth (Green analog looking box/charger) then I can't see how you can compare this with an official M401, unless it really is a M401. The threads are close enough so they will work, but not very well. There's such a large gap between the Health Atty and the M battery that when you draw, you'll get a large volume of air with little to no vapor. BTW my "Health" model had a thin, sharp wicking bridge (for piercing the foil covered carts) so if the Heath model your talking about has a wide, curved bridge then disregard my comment.
As for the EVO vs the Pilot/M401 ect... I'm just not that convinced that they're modified at all. Personally i see no difference between my factory units, PS's Pilot, or Intellicig's EVO. (I have at least 8 M401 Kits, including 2 EVOs)
